Storrick Multihooks

Overview


Version A
(#957)

Front Rear

Technical Details

I made this Multihook in 2004, but the design dates from about 1980.

I milled this Multihook from 1/2-in (12.7 mm.) 6061-T6 aluminum.

Comments

The idea behind the Multihook was to create a device that functioned like a Figure Eight descender, but does not need to be unclipped for rigging or derigging. The Frendo canyoneering Eights provide one nice solution to this problem, but they don't pack as well as a flat eight. I started working on the ideas in the early 1980s, and long before I made these, I'd come up with the ideas for the Open Eights. At this point in time, I don't take the Multihook too seriously, although it does work. One does need to take care, since the rope can come out of the device if one is careless.

Since I don't have a CNC milling machine, I resorted to stacking two rotary tables so that I could make the side, ear, and eye cuts in a single setup (think about it!). The round eye at the bottom resulted from a machining error (I got my sequence messed up and turned the wrong rotary table).

Comments

The idea behind this Multihook is similar to the first, except that it functions more like a Sidewinder, Longhorn, or TCS than a Figure Eight. Like these devices (and Version A), it does not need to be unclipped for rigging or derigging. This design also comes from in the early 1980s. Like Version A, I don't take this version too seriously, although it too does work. One still need to take care, since the rope can also come out of the device if one is careless.

I milled the side slots with a normal setup, and then used stacked rotary tables like I did for Version A. This time I turned the rotary tables in the proper sequence, and the eye came out like I planned.
